Title: Improvements in and relating to boxes and method of making the same
IPC: B31B15/00
Filed: 1922-01-03
Abstract: 195,175. Smith, H. B. Jan. 3, 1922. Covered boxes; boxes made from special blanks. - In forming covered boxes having a body portion, side wings, end wings and corner or end laps, a strip of shell material W, Fig. 1, having rectangular spaced apertures w is adhesively connected to a cover strip x and the combined strips are severed solely on a single transverse line 15 thus giving a covered shell blank A, Fig. 2, with adhesively ccated marginal portions z of the cover extending beyond that part of the shell material forming the end wings 22; alternatively a separate shell blank having rectangular end portions removed may be adhesively connected to a cover blank to give the same covered shell blank. The marginal porticns x of the cover material are turned over and pressed into adhesive contact with the margins of the shell material and either before, during, or after assembly the shell material or both the shell and cover material is scored along the subsequent folding lines 12, 13. After assembly the covered strip or blank is cut along lines 24 to form the end or corner laps 23. The completed box, shown in Fig. 7, is formed by first turning up the side wings 21 and connected end laps 23, then turning in the end laps, the under surfaces of which are coated with adhesive 25, then folding up the covered end wings 22 and finally turning the margins z over the end laps and pressing them into position; or the end wings 22 and their covering may be separated and the corner laps turned in between them so as to cover the vertical edges of the shell end wings. The vertical edges of the shell end wings are left exposed in the first method, and may be made less conspicuous by pressure exerted by a suitable corner presser.

Title: Liquid fuel control means for jet-propulsion engines
Inventor: LAWRENCE OWEN NAPIER
IPC: F02K3/00
Filed: 1952-01-02
Abstract: 712,775. Gas turbine plant. LUCAS (INDUSTRIES), Ltd., J. Jan. 1, 1953 [Jan. 2, 1952], No: 131/52. Class 110(3) [Also in Group XXIX] Means for preventing a temporary excess of fuel to a jet propulsion engine during acceleration comprise means adapted to control a liquidoperated servo-mechanism which controls the output of the engine fuel pump or otherwise regulates the fuel supply to the engine and means responsive to fluid pressure differences derived from the pressures at the inlet and outlet of the blower and at least the outlet of the turbine for controlling the servo-mechanism. In Fig. 1, the casing a has two chambers b, c. The chamber b is divided into two compartments by a flexible diaphragm (or piston) d and likewise a diaphragm (or piston) e divides the chamber c into two compartments. The diaphragms act at opposite ends of a lever f pivoted between the chambers. The diaphragm d acts through a further lever h and a ball or roller i adjustable by a screw k. The pressure rise across the turbine-driven blower 6 is applied to the diaphragm d through pipes 9, 10 and the pressure drop across the turbine 5 which drives the blower is applied to the diaphragm e through pipes 11, 13. The pipe 11 may have a restriction 12. The lever f is also connected to a lever n carrying a vent valve q controlling a pipe s leading from the servo-cylinder v. The latter is supplied with liquid (which may be the liquid fuel) through a duct x and contains a spring-loaded piston t the rod y of which actuates the pump output or other fuel control means. The valve q is normally closed, but if during acceleration, the pressure rise across the blower exceeds the pressure drop across the turbine, the vent valve q is opened to cause the fuel supply to be reduced. In a modification, the lever f itself carries the vent valve and the diaphragms act in opposite directions on the same side of the fulcrum of the lever one diaphragm being responsive to the difference between blower outlet pressure and turbine outlet pressure and the other being responsive to the difference between turbine outlet pressure and blower inlet pressure. In Fig. 3, the lever f carries the servo vent valve q and is actuated by the diaphragm e only, this diaphragm being exposed to turbine outlet pressure through a connection 13 and also to a pressure proportional to the blower delivery pressure in a chamber between the diaphragms d, e. This chamber has a restricted outlet 20 and an inlet duct 10 connected to the blower outlet. The outlet of the duct 10 is controlled by a valve 17 connected by a yoke 18 to the diaphragm d. The diaphragm d is exposed to the blower inlet pressure through a connection 9 and to the pressure in the intermediate chamber proportional to the blower outlet pressure.
